Abstract
A liquid crystal dispensing apparatus includes a needle sheet formed as a unitary piece for dispensing liquid crystal material contained within a liquid crystal container through a nozzle by selectively contacting a needle. The needle sheet includes a needle contacting portion for contacting the needle and a coupling portion for coupling the liquid crystal container to the nozzle. Therefore liquid crystal material is prevented from remaining within the needle sheet and the needle sheet can be easily cleaned.
Claims17
A liquid crystal dispensing apparatus comprising:
- a liquid crystal container for containing liquid crystal material and gas wherein the liquid crystal material does not occupy the liquid crystal container;
- a case receiving the liquid crystal container;
- a needle inserted into the liquid crystal container, the needle having a first end and a second end and for movement along an axis of the liquid crystal container;
- a spring arranged on the first end of the needle;
- a needle sheet arranged at a lower portion of the liquid crystal container for coupling the liquid crystal container to the case, the needle sheet comprising a discharging hole, wherein the needle contacts a portion of the needle sheet surrounding the discharging hole;
- and
- a nozzle coupled to a lower portion of the liquid crystal container by the needle sheet, the nozzle including a discharge opening through which liquid crystal material in the liquid crystal container is dispensable onto a substrate.
A needle sheet of a liquid crystal dispensing apparatus, comprising:
- a coupling portion for coupling a nozzle to a liquid crystal container of a liquid crystal dispensing apparatus;
- and
- a needle contacting portion, wherein the needle contracting portion and the coupling portion are formed as a unitary piece, the liquid crystal dispensing apparatus comprising a needle for inserting into the liquid crystal container for selectively contacting the needle sheet such that liquid crystal material is selectively dispensed through the nozzle onto a substrate.
A unitary coupling component, comprising:
- a coupling portion for directly contacting a container;
- a needle contacting portion adjacent the coupling portion for directly contacting a nozzle;
- and
- a discharge hole in communication with an opening in the nozzle, wherein the coupling portion and the needle contacting portion are formed as a unitary piece, and wherein material within the container exits the container through the discharge hole and the opening in the nozzle.
